LUG FOR SILOS AND THE LIKE.

Specification of Letters Patent.

Patented J an. 16, 1917.

T 0 all whom it may concern Be it known that I, EMIL C. TnoK'roNiUs, a citizen of the United States, residing at Racine, in the county of Racine and State of iVisconsin, have invented certain new and useful Improvements in Lugs for Silos and the like, of which the following is a specification, reference being had to the accompanying drawing, formin a part thereof.

This invention relates to hoop or band lugs for silos, kilns, tanks and similar structures and the objects of the invention are to improve such lugs in the manner to be hereinafter described and claimed.

Referring to the drawings which accompany this specification and form a part hereof, which drawings illustrate an embodiment of this invention and on which drawings the same reference characters are used to designate the same parts wherever they may appear in each of the several views, Figure 1 is an elevation of two of the lugs and associated parts; Fig. 2 is a vertical, longitudi nal section of a lug, showing the associated parts in their operative positions; Fig. 3 is a plan view of a lug and associated parts, and Fig. 4; is an end elevation of a lug.

Referring to the drawings, the reference numeral 1 designates a silo or similar structure, 2 and 3 lugs, 4 a hoop or band provided with screw threaded ends and which may be composed of a single section or a plurality of sections joined together in any suitable manner, and 5 a tie rod.

The bases of the lugs illustrated by the drawings are provided with screw or bolt holes 6 by means of which the lugs can be secured to the structure with which they are.

to be used. It is convenient in building silos, for example, to assemble the frame for the door opening upon the ground and attach the lugs to this frame before it is raised into place and the lugs illustrated by the drawings are especially useful in constructing silos in this manner.

The tie rod 5 spans the door opening in the silo and also serves as the rung of a ladder so that a person can climb up or down a silo by stepping upon the tie rods. The lug and associated parts illustrated by Fig. 3 of the drawings are seen in the positions which they occupy when in place on a silo. The lugs and associated parts illustrated by Fig. 1 of the drawings are seen in the positions which they occupy on a silo when viewed from above and the parts illustrated by Fig. 2 of the drawings are seen in the positions which they occupy on a silo when viewed from below.

The ends of the hoop or band 4: are provided with nuts 7, spiral springs 8 which are of the open or compression type, and eveners 9 and 10. The springs 8 yield when the silo or structure expands, and, when the structure contracts, the springs expand and pull the hoop or band into the lugs and keep the hoop or band tight and under tension around the structure at all times.

The lug is formed as an integral casting and is composed of a base 11, a rear wall 12, a front wall 13 and an arch 14. The arch let springs from the base and is provided with an ear 15 and is connected with the base and the rear wall 12 by a curved web 16 and with the base and front wall 18 by the webs 17 and 18. The rear wall 12 is provided with an aperture 20 which is elongated in the direction of a diameter of the structure to which the lug is to be applied and the ear 15 is provided with an aperture 19 for a tie'rod 5. The arch let is located between the front and rear walls and is nearer the front wall than the rear wall so as to provide an aperture 21 large enough for the end of the hoop and the spring to pass freely therethrough and to permit the end of the hoop and the spring to be rocked within said aperture to the extent permitted by the elongated aperture 20 in the rear wall 12. The apertures 20 and 21 are in line with each other so that the end of the hoop can extend therethrough in a line substantially tangent to the structure with which the lug is used, and the elongated aperture 20 in the rear wall 12 permits the hoop to occupy different positions in this aperture according to the size of the structure.

The screws or bolts which pass through the screw or bolt holes 6 are intended to locate the positions of the lugs but are not intended to withstand strains to which the lugs are subjected. The lugs are formed as rights and lefts so that when in use the ears 15 will aline for a tie rod. The function of the lugs is to connect the ends of the hoop 4 with a tie rod 5 and the tie rods, the hoops and the lugs bear all the strain exerted by the springs 8 and any additional strain which may by chance be imposed upon them.

The ends of the tie rod 5 are screw threaded and are provided with nuts 22 against which the ears 15 of the lugs hear. The strains are imposed upon the ears 15 and the rear walls 12 of the lugs and to tie these parts together so as to withstand the strains with the use of the minimum amount of material the curved web 16 is provided and is united with the rear wall 12, the base 11 and the arch 14 to form a tension member supplemental to the base. The webs 17 and 18 and the front wall 13 act as a brace between the base of the lug and the arch 14:. The arch 11 is illustrated by the drawings as being thicker than the curved web 16 and a strengthening rib 23 is shown running from the ear 15 and merging into the curved web 16 for additional strength. The base is formed with a rectangular opening as clearly shown by Fig. 2 of the drawings for convenience in forming the molds for casting the lugs.

The lugs are preferably formed from castiron and are then treated to make them malleable and the construction illustrated and described provides very strong and durable lugs which are light in weight and comparatively inexpensive.

hat is claimed is:

1. A hoop or band lug for silos and the like consisting of an integral casting having a base, an apertured rear wall, an arch springing from the base and provided with an apertured ear, and a curved web tension member connecting the arch with the base and the rear wall.

2. A hoop or band lug for silos and the like consisting of an integral casting having a base, an apertured rear wall, a front wall, an arch springing from the base between the front wall and the rear wall and provided with an apertured ear, a curved web tension member connecting the arch with the base and the rear wall, and bracing webs connecting the arch with the base and front wall.

3. A hoop or band lug for silos and the like consisting of an integral casting having a base, a rear wall provided with an elongated aperture, a front wall, an arch springing from the base between the rear wall and the front wall and leaving an aperture between it and the front wall so that a hoop or band can extend through said aperture and the aperture in the rear wall in a line substantially tangent to the structure to which the lug is applied, the arch being provided with an apertured ear, a curved web tension member connecting the arch with the base and the rear wall, and bracing webs connecting the arch with the base and the front wall.

In Witness whereof I hereto afliX my signature.
